Netspeak     

Hello, I'm your Mike.
Please tell me your boat name.

That's it, just your Boat Name Only and wait to
be recognized by Net Control or a Relay before   saying anything more.

Chaos is Averted and it's a great day at sea.
Thanks guys.
.

Use "Contact" to make contact with a Short-Time Vessel.
Your friends on "Windsong" just checked in short-time.
You want to catch them before they sign off.
Now is the time to say "[your boat name] Contact."

It's considered intrusive to jump in with
"Traffic/Contact" at random.
Be patient and use Traffic when you check in: 

"This is Fluffy, in Charleston, and I'd like traffic."
Simple, clean and Net Control will be your friend.

Break

"I've got something critical to add right now."

Break Break

"This is an emergency."   A double break, yikes! ... sinking or afire??

Clear

"I'm finished with my transmission."
"I'm moving to another frequency."

Contact ~ See Above

Info

"I've got information about that."

Out

"I'm signing off."

Propagation Check

Please hold off until the end of the net so it may continue to move along smoothly.  Or better yet, bring your query to the Tech Net.

Radio Check

Not used much. A VHF term, but you knew that.

Relay

Use the word Relay and your Boat Name when you're hearing another boat trying to check in that the Net Control is obviously not hearing.
It's incredibly helpful and you're a darned good person.
As in: "Relay boat name."

Stand By

"Please wait."

Traffic ~ See Above

Underway

"I'm actively moving; no longer anchored or docked."

Query

"I have a question or need information."
